METALLIC HARROWI.

SPECIFICATION forming part Of Letters Patent No. 623,082, dated April 11, 1899.

Application filed March 21 1898.

To all whom it may concern:

Be it known that I, RALPH T. HORNING, a citizen of the United States, residing at New Philadelphia, in the county of Tuscarawas and State of Ohio, haveinvented new and useful Improvements in Metallic I-Iarrows, of which the following is a specification.

My invention relatesto improvements in barrows; and it consists of a new and novel method and means of mounting and supporting the teeth thereof.

Figure 1 is a perspective view of the toe of the harrow, showing the method of attaching the angle-iron thereto and the means of IS mounting and supporting the teeth therein. Fig. 2 is a sectional view through the toe, showing the method of inclining the teeth.

In the accompanying drawings similar letters of reference refer to similar parts.

A is a metallic toe of one of the points of the harrow, the harrow proper being made up of three substantially A-shaped sections. The metallic toe is substantially V-shaped, having the flanges aa alongits sides, to which are bolted the angle-irons B and B. Across the center of the toe A there is a projecting flange a for the purpose of carrying the clip supporting the barrow-tooth. Through the. forward part of the toe there is provided an 0 aperture a having a larger opening at. the top than at the bottom and its forward side slanting. Through the forward part of the toe and the aperture there is drilled a hole a through which passes a bolt 0. to engage 5 with and hold the forward tooth 0 when it is locked in .an inclined position.

To providea means for locking the forward tooth Gin a perpendicular position, two holes a a are drilled in the upright-projecting lug a through which there is passed a U shaped clip D, screw-threaded upon its ends and, being passed around the tooth and projecting through the holes in the lug a is held in position by nuts engaging the screw-threaded ends thereof.

To the metallic toe A and on either side thereof there are securely bolted angle-irons having elongated openings 19 through the lower flange thereof, and in the upper or per- Serial No. 674,557. (No model.)

pendicular flange there are provided round openings 6', b and b for engaging the clip D in its various adjustments. When it is desired to clamp the tooth O in perpendicular position, the clip D is passed over the tooth C and through the apertures b and b and upon the screw-threaded ends thereof are placed retaining-nuts b and b and thus the tooth is clamped securely against the upper or vertical flange. lVhen it is desired to adjust the tooth Gin its inclined position, the elongated opening Z) being longer than the Width of the tooth, the tooth is inclined therein and the clip D passed over the tooth and the ends thereof through the apertures 17 and b and is retained and locked in that position by means of the retaining-bolts b and 12 As heretofore referred to, I have shown my invention as applied to one form of harrow; but the same is capable of being applied to a harrow in which parallel rails or bars are used, or cross-bars.

Heretofore it has been exceedingly difficult to provide a simple and positive means of holding the tooth in its engagement with the bars of the harrow or to provide any satisfactory means of inclining the tooth. My invention overcomes all these difficulties and at the same time provides a simple and positive means of locking the tooth to the bars, and the same instrumentality also performs the same function when the tooth is inclined.

Having thus fully described my invention, what I desire to claim by Letters Patent is- 1. A metallic toe for a harrow,havin g flanges for engagement with the tooth beams or bars, an elongated opening-in the point thereof, and means for locking the tooth therein, either in a vertical or inclined position, substantially as described and for the purpose set forth.

2. A barrow-tooth adjustment consisting of a block having an opening with an elongated upper end, and a clip adapted to hold the tooth against the front or the rear wall thereof for the purpose of effecting an adjustment of the tooth, substantially as described.

3. A barrow-tooth adjustment comprising 4 a block having a vertical opening, one Wall In testimony whereof I have hereunto set of the opening beinginclined, both walls havmy hand in the presence of two subscribing ing clip-openings, and a clip adapted to pass witnesses.

through the openings of either Wall and t0 RALPH T. HORNING. clamp the tooth thereagainst for holding it in Witnesses:

a vertical or an inclined position, substan- J. F. STEPHENSON,

tially as described. 1 H. P. FRIBLEY.
